Pull request overview
Fixes flakiness in LoggingHandlerTest.testLogLevelHandlerOutput by ensuring logger instances are strongly referenced so Log4j2’s weakly-referenced logger cache doesn’t allow loggers to be GC’d and recreated mid-test.
Changes:
- Add strong
Loggerreferences for the relevant logger names used by the test. - Update “effective level” assertions to use the held logger instances instead of repeated lookups.
- Minor comment text adjustment.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Minor grammar issue in the comment: "...and with its effective values" reads awkwardly and seems to be missing a verb. Consider rephrasing to "...and what its effective values are" (or similar) for clarity.
| // ...and with its effective values | |
| // ...and what its effective values are |
| // check directly with log4j what its (updated) config has... | ||

This block corrects "it's" → "its" here, but a similar comment later in the UNSET section still uses "what it's (updated) config has...". Please update that occurrence too to keep wording consistent.
